' AUTOMOBILE HEATER.

Application filed March 22, 1926. Serial No. 96,607.

This invention relates to heaters and has special reference to an automobile heater.'

One object of the invention is to provide an improved 'and economical automobile heater arranged to use water or other suitable liquid heated by the hot gases flowing through the exhaust pipe common to auto= mobiles using internal combustion engines.

A second object of the invention is to provide an improved heater of this description so arranged as to avoid the use of valves.

A third object of the invention is to pro-- vide an improved, arrangement of water storage tank inconnection with such heaters.

With the above and other objects in view as will be herein apparent, the invention consists in general of. certain novel details of construction and combinations of parts hereinafter fully described, illustrated in. the accompanying drawings and specifically claimed. H

In the accompanying drawings like char-- acters of reference indicate like parts in the several views, and:

Figure 1 is a section through the forward lower part of an automobile body showing the improved heater installed therein.

Figure 2 is an enlarged detail partly in section showing the water heating drum and the pipes connected thereto.

Figure?) is a plan view of the heater c'oil fislit rests on the foot board of the automo- Figure 4 is an enlarged detail section on the line 4-4 ofFigure 2.

Figure 5.is'a section through the. upper partof the water storage tank showing the filling plug and vent.

In the present showing there is disclosed a portion of an automobile including the floor board 10, dash 11, foot board 12, exhaust pipe 1-3 and muflier 14, theexhaust pipe leading in the'usual manner from the exhaust manifold ofthe engine (neither a vent 19. Extending from the bottom of I this tank to the bottom of the drum 15 is a supply pipe 20 and the tank is likewise provided with an overflow or relief pipe 21 leading from the top thereof. Laid fiat upon the foot board 12 is a heater coil 22 formed of sinuously bent tubing and having one end 23 continued to connect with the top of the drum and'form a flow pipe while its other end 24 is likewise continued'and is connected with the bottom of'the drumto form a return pipe.

In operation it will be'seen that the drum and coil with its connecting ends will always remain full so long as there is water in the tank and that whenever the exhaust is hot a flow will be set up by convectionthrough the coil.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified. Having thus described the invention, what is. claimed as new, is:'

1 The combination with an automobilebody and an automobile exhaust pipe; of a heating drum surrounding the exhaust pipe, a heating coil within the body, a flow pipe connecting one end of the coil to the top of thedrum, a return pipe connecting the remaining end of the coil to the bottom of the drum, a supply tank carried by the body at. a greater elevation than said coil, a supply pipe lea-ding directly from the bottom of the tank to the bottom of the drum, and a relief pipe leading downwardly from.the top of'th'e tank. i d

2. The combination with an automobile having a body "provided with a dash and foot board and having an exhaust pipe and a mufiier connected thereto;. of aheating drum surrounding said exhaust pipe forward of the mufiier toreceive a maximum of heat from the. exhaust pipe, a flat-heating coil mountedonthe foot board, a flow pipe leading from oneend of thecoil to the top of the drum, a return pipe leading from the remaining end of the coil' tothe bottom of the drum, a supply tank carried by the dash above the foot board, and-a supply ipe dir rectly connecting the bottoms of t e tank and drum In testimony'whereof I afiix m signature.
